The age range with the lowest vitamin B12 levels in both female and male children was found to be 14-18 years (p<0.001). Vitamin B12 deficiency and borderline deficiency were mostly seen in August and July (p<0.001). Conclusion: Vitamin B12 deficiency and borderline deficiency were observed ...
For this reason, I don’t include a vitamin B12 levels chart on this page. Basically, all of the charts I’ve seen show very low vitamin B12 levels as normal. Perhaps in time charts will reliably show healthy vitamin B12 levels. That could, however, interfere with sales of certain prescr...
叶酸与维生素B12是核苷酸和氨基酸生物合成的必需营养素,还与贫血、心脑血管疾病的发生显著相关。同时,由于糖尿病患者中由于二甲双胍的使用会影响维生素B12水平,2型糖尿病患者维生素B12缺乏的发生率高于一般人群。然而,机体叶酸及维生素B12水平与2型糖尿病患者心脑血管疾病死亡风险存在怎样的剂量-反应关系,目前尚不清楚。该...

OBJECTIVES: The aim of this study was to determine vitamin B12 levels in patients with non-pulsatile tinnitus and to assess the efficacy of replacement treatment in tinnitus and hearing in patients with vitamin B12 deficiency. MATERIALS AND METHODS: We assessed 100 patients (mean age, 43.87, SD...
The vitamin B12 levels of cerebrospinal fluid were assayed microbiologically (Lactobacillus leichmannii method) using samples from 44 patients with various neurological disorders, 4 patients with megaloblastic anemia and 34 controls. Twenty-seven controls that did not receive vitamin B12 showed a mean ce...
Vitamin B12 concentration was determined by radioassay in 179 healthy volunteers between the ages of 20 and 93 years in order to determine whether vitamin B12 levels decline with advancing age. The authors found no statistically significant decline in vitamin B12 levels in older individuals, nor a ...
B12 levels, bound vit. B12 levels, and urinary excretion of vit. B12 compared in the 2 groups. Concentration of free vit. B12 was higher in the group receiving crystalline vitamin. Over the 24-hour period, percentage of bound vitamin serum was greater in the group receiving liver extract. ...
1. Vitamin B12 levels were determined in centipede, millipede, spider, isopod, leech, earthworm, tubifex worm, snail, clam and shrimp. All contained appreciable amounts of vitamin B12, which ranged from 19 to 4013 pg/mg dry wt. 2. 2. The metabolism of (2-14C)propionate was examined in...
